ITMS-90683: Missing Purpose String in Info.plist NSCameraUsageDescription

For NSCameraUsageDescription, Add the exact purpose of using camera in the Value column.For example,

Folks are saying they're getting rejected even though they're not request access to camera. You have to know that Apple will scan your code with their static analysis tools. And even if you have this protected behind a feature flag, still the app store review process would reject your app. Because they don't know when you'll turn that feature flag on.

Additionally you could get this issue if a third-party service has a camera access related code in their code. Again even if you don't hit that line (of the 3rd party framework), you'd need that key in.

But then I've had issues where we've added that plist in, but then the app store review team was never able to test it out because the feature was protected by a feature flag. And because they couldn't test it, they didn't approve it ¯\ (ツ) /¯

Last but not least, if you did really need that key in your plist, then make sure its reasoning is generic enough to cover all cases e.g. If you need access to the camera for both take profile pictures and scanning QR code, then given that your app can request access for the camera at either the profile picture step or at scanning a PR code, then your description in the plist should cover both features, not just one of them. If you say "need access to take profile photos" then there is a chance that you could rejected if user hits the QR flow first but sees you're requesting access to take a profile photo. Hence you should say "need access to take profile photos and QR code scan for new devices"

tl;dr identify where in your app flow you're requesting access. If you need it then add its key/value in your plist. If you don't need it then comment out that line. You shouldn't just add the plist just for the sake of passing an app store review. It could fail but it also can happen to succeed, but then in a future release it would succeed...
